Early percutaneous closure of iatrogenic cardiac defects following multiple valvular surgery with direct guidewire support is a potentially curative technique with demonstrable clinical improvements

Transcatheter closure of a huge iatrogenic atrial septal defect: A case report

RATIONALE

Iatrogenic atrial septal defects caused by cardiac surgery are rare complications that are traditionally repaired through reoperations; unfortunately, reoperations are accompanied by high risk and trauma.

PATIENT CONCERNS

Herein, we report a rare case of a huge atrial septal defect after mitral and aortic mechanical valve replacement.

DIAGNOSES

Transesophageal echocardiography revealed a 20 × 33 mm atrial septal defect with a mainly left-to-right shunt and bidirectional shunt.

INTERVENTIONS

The defect was successfully occluded using a Shape Memory septal occlude with a waist diameter of 42 mm.

OUTCOMES

At follow-up 6 months after, the patient's symptoms were remarkably relieved and chest radiograph showed obvious improvement of the pulmonary congestion.

LESSONS

Percutaneous device treatment can be used as an alternative to surgery in iatrogenic atrial septal defects if the anatomical condition of the septal defect is appropriate for transcatheter closure.
